The daemon can apply a configuration change to the following parameters without a restart:
sap_interval, syslog_proto, syslog_server, log_severity, sample_rate
The daemon can apply a configuration change to the following parameters without a light restart:
http_port, rtsp_port, http_base_dir, rtp_mcast_base, sap_mcast_addr, rtp_port, rtp_port, status_file, interface_name, mdns_enabled
A light restart means that the configuration can be applied without interrupting the playback/capture applications
A change to one of following paramters causes a full daemon restart:
interface_name, tic_frame_size_at_1fs, max_tic_frame_size
On PTP status change the daemon can run in background an external shell script whose path name is specified by the new ptp_status_script Config parameter.
If this parameter is empty, no script is invoked. The PTP clock status is passed as first parameter to the script and it can be unlocked, locking or locked.
A sample script is provided in daemon/scripts/ptp_status.sh
- modified SessionManager class to register and trigger observer callbacks when a new session is added or removed
- moved MDNSServer out of the SessionManager and added instantiation in the daemon main
- MDNSServer instance registers to SessionManager to receive source add & remove events and invokes appropiate Avahi client operation
- RTSPServer instance registers to SessionManager to receive source update events. In case of update It sends RTSP ANNOUNCE (with the new SDP) to the connected RTSP clients that previously requested (via DESCRIBE method) the SDP file for the specific source
- removed disconnetion timeout handling in RTSPServer. RTSPServer connections are now persistent
- mDNS advertisement for all local Sources is implemented by mdns_server.[cpp,hpp] and based on Linux Avahi.
- RTSP server implementation supports DESCRIBE method to return SDP of local Sources and supports persistent connection but doesn't provide service updates via UPDATE method.
- Modified RTSP client to browse for _ravenna_session subtype of _rtsp._tcp services only.
- Modified SAP and mDNS discovery to avoid returning local Sources advertised by the daemon.
- Added "rtsp_port" and "node_id" config parameters.
- rtsp_port is a read/write parameter that contains the port of the RTSP server.
- node_id is a read only parameter that contains the unique daemon identifier used in mDNS and SAP sources announcements.
- Modified session manager to check that every Source and Sink created by the user has a unique name.
- Modified WebUI to visualize node_id and to visualize and edit rtsp_port parameters in Config tab.
- Extended regression test to verify proper behaviour of mDNS/RTSP sources advertisement and discovery.
- Modified REST API to browse remote sources to allow browsing of SAP, mDNS and all sources via HTTP GET /api/browse/sources/[all|mdns|sap].
- Amended daemon documentation.
